MACHINE FOR ROLLING BLANKS FOR SHOVELS, 800.

SPECIFICATION forming part of Letters Patent No. 340,953, dated April 27,1886.

Application filed March 27. 1885. Renewed April 5, 1886. Serial No. 197,884. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY M. MYERS, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Rolls for Manufacturing Blanks for Shovels, Spades, and Scoops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the means hereinafter described for manufacturing blanks for making shovels, spades, and scoops.

To enable others skilled in the art with which my invention is most nearly connected to make and use it, I will proceed to describe its construction and operation.

In the accompanying drawings, which form part of this specification, Figure l is a front elevation'of a pair of rolls for making indentations and projections on one edge of a heated fiat bar. Fig. 2 is a vertical and transverse section of the same at line a: of Fig. 1. Fig. 3 is a top view or plan of a flat bar of iron or steel after passing through said rolls. Fig. 4 is a blank for a shovel, spade, or scoop-that is, it represents in perspective a section of the bar shown in Fig. 3.

Vhen the billet is heated to the proper degree for forging, it is removed from the furnace and passed through rolls of the ordinary construction for reducing it to a fiat bar, which, while in the heated condition, is passed through one of the grooves A of the roll B, in the bottom of which grooves are a series of indentations, 0. (Shown plainly in Fig. 2.) By passing the flat bar D through the groove A in the roll B a series of indentations and projections are formed on one edge of it by the impinging action of the two rolls, B E, as indicated in Fig. 2, whereby a bar is formed having projections F on one edge ofit, as shown in Fig. 3. which bar is cut into sections, as indicated by the dotted lines shown in Fig. 3, each section forming a blank (shown in Fig. 4) for the making of a shovel, spade, or scoop by any of the several methods known to the art.

The bar herein shown and described is claimed in another application filed herewith, Serial No. 160,244. 7

Having thus described my invention, what I claim is The upper plain roll in combination with the lower roll having one or more grooves provided with a series of indentations properly spaced to form projections on the edge of a bar of metal, substantially as described.

HENRY M. MYERS.
